Description

Technical Field

[0001] This invention belongs to the field of urban and rural planning technology, specifically relating to a method for compiling holographic guidelines for the urban and rural physical space renewal process. Background Technology

[0002] Currently, my country has entered a new stage of high-quality development. At the end of 2021, the urbanization rate of the permanent resident population reached 64.72%. High-quality renewal of urban and rural physical spaces has become an important means to meet the people's growing needs for a better life and promote the full development of urban and rural areas. From the perspective of employment distribution, urban and rural physical spaces are important carriers of employment opportunities, profoundly influencing the types of employment activities; employment activities also directly or indirectly affect the state of urban and rural physical spaces, and changes in employment activities are one of the important reasons for the renewal of urban and rural physical spaces. Given the vast scale and diverse conditions and foundations of urban and rural physical spaces in my country, there is an urgent need for scientific and reasonable guidelines for urban and rural physical space renewal to guide the rational distribution of employment opportunities in urban and rural areas.

[0003] In recent years, there has been a wealth of research and practice in my country regarding urban and rural renewal guidelines, with typical related studies shown in Table 1. Firstly, the compilation of urban and rural renewal guidelines has become an important topic in academia. Regarding urban renewal, Yang Junyan et al. (2011) combined two-dimensional urban land use attributes with three-dimensional urban spatial morphology from the perspective of intensive land use, exploring the compilation technology of old city renewal planning guidelines based on grasping the overall image of the land parcel through a sub-control system. Hua Fang et al. (2013), focusing on the protection and renewal of Hangzhou's old city, proposed a method for compiling planning and design guidelines by combining "system framework with planning compilation and management" and "content-limited rationality with flexible control." Song Li (2015), aiming at map-based management, proposed a planning technology compilation system combining control planning and urban design guidelines. Through "control planning + map-based urban design," she explored the technical compilation system and practical path from intentional urban design to map-based urban design, guiding regional development and improving the refined management of urban form. Cheng et al. (2021) explored a standardized protection plan compilation system for the protection of courtyard houses in Qingdao, using a combination of text and graphics, covering aspects such as basic information, functional guidance, protection scope, protection objects, value elements, and protection measures. Regarding rural renewal, Tu et al. (2020) took Zhangyan Village in Chonggu, Shanghai as an example, exploring a path for compiling guidelines for the renewal of traditional villages through a three-tiered flexible control intensity guidance and a negative list governance model. Secondly, the national and local governments have also issued several standards to guide urban and rural renewal guidelines. For example, the "Standards for the Protection Planning of Historical and Cultural Cities" (Ministry of Housing and Urban-Rural Development, 2018) stipulates the spatial elements and renewal methods for the protection and renovation of historical and cultural blocks and community living areas; the Shenzhen Municipal Planning and Resources and Land Resources Commission (2018) issued the "Technical Regulations for the Compilation of Urban Renewal Unit Plans in Shenzhen."

[0004] Table 1. Overview of Spatial Elements and Renewal Methods in Research Related to the Guidelines for Urban and Rural Spatial Renewal

[0005]

[0006] There are also some typical practices in foreign urban and rural renewal guidelines. For example, in the Paris Local d'Urbanisme (PLU, 2001), the key contents of urban and rural renewal include coordinating the relationship between the city and the surrounding areas, adjusting and improving urban functions, improving the quality of urban life, and repairing the urban spatial fabric. Apollo M et al. (2012), taking the urban renewal project in Gničar, Poland as an example, explored the method of urban renewal map preparation for renewal goals such as the modernization of residential buildings and public spaces, new road construction, and incentives for local residents. Stephanie Judge et al. (2020) explored innovative expressions of detailed development plans, using the application of three-dimensional interactive maps to present the plan drawings in a three-dimensional and visual way, while simultaneously meeting the needs of public participation and comparison of multiple schemes.

[0007] However, existing methods for developing urban and rural renewal guidelines still need improvement. Firstly, in terms of applicable objects, insufficient emphasis is placed on urban and rural physical spatial elements. Existing guidelines primarily focus on urban spaces, especially historical towns and districts, and their adaptability to rural spaces needs further testing. In particular, the fundamental role of tangible urban and rural physical spatial elements needs strengthening. Urban and rural physical spaces are crucial starting points and endpoints of urban renewal, and also important means for urban and rural planning to intervene in socio-economic development. Some classification methods for physical spaces do not yet comprehensively cover the entire space without redundancy or omission. This falls short of the current needs for integrated urban and rural development, rural revitalization, and full coverage of territorial spatial planning, making it difficult to adapt to the requirements of refined and high-quality urban and rural spatial renewal. Secondly, in terms of renewal methods, a systematic map of renewal methods needs strengthening. Existing guidelines primarily focus on renewal strategies for buildings and structures, and renewal methods for other physical spatial elements need further refinement. In terms of the degree of renewal, the guidelines do not systematically cover the different needs from preservation to demolition and new construction. Furthermore, in terms of the expression of outcomes, the expression of the renewal process needs improvement. Existing update guidelines mostly focus on expressing or guiding the update results, but they still struggle to answer how urban and rural physical spaces transition from one state to another. Summary of the Invention

[0008] To address the aforementioned issues, this invention provides a holistic guideline compilation method for the urban and rural physical space renewal process. Building upon existing methods for compiling urban and rural renewal guidelines, this invention focuses on the renewal process of urban and rural physical space, proposing a holistic approach to compiling the core content of urban and rural physical space renewal guidelines. The renewal process is reflected in the state and changes of various urban and rural physical space elements before and after the renewal, clearly illustrating how urban and rural physical space transforms from one state to another, specifically utilizing GIS technology through a combination of charts and graphs. The holistic nature is first reflected in the comprehensive coverage of urban and rural physical space types and elements: firstly, it covers both urban and rural areas; secondly, it covers all directly observed and perceived important spatial elements of urban and rural planning and control, encompassing the entire urban and rural space from a planar projection perspective; and thirdly, it is reflected in the renewal methods, establishing a spectrum of renewal methods from preservation to new construction based on the degree of renewal. The core content focuses on the renewal process, expressing the spatial structure and attributes of physical space elements through a combination of charts and graphs. This method further enhances the scientific rigor and practicality of urban and rural renewal guideline compilation.

[0028] The method for compiling holographic guidelines for the urban and rural material space renewal process according to the present invention has the following outstanding advantages:

[0029] 1) Based on the existing classification of urban and rural material space, from the perspective of direct observation, urban and rural material space elements are divided into multiple types that fully cover the target area, so as to achieve full coverage of ordinary urban and rural material space elements.

[0030] 2) Based on existing renewal methods, a renewal strategy for urban and rural material space elements is established from two dimensions: the internal and external dimensions of the renewal objects—the constituent elements of urban and rural material space—and the degree of renewal, to achieve full-element and full-process coverage of urban and rural material space renewal methods. A spectrum of renewal methods is defined based on the types of urban and rural material space elements before renewal, renewal strategies, and types after renewal.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following describes in detail the method for compiling holographic guidelines for the urban and rural material space renewal process of this invention, in conjunction with embodiments and accompanying drawings.

[0041] <Example>

[0042] Figure 1 This is a flowchart of the method for compiling holographic guidelines for the urban and rural material space renewal process in this embodiment.

[0043] like Figure 1 As shown, the method for compiling holographic guidelines for the urban and rural material space renewal process in this embodiment specifically includes the following steps:

[0044] Step S1: Standardize the existing topographic survey map and planning design map of the target area in dwg format into a distribution map of urban and rural material spatial elements;

[0045] It is divided into 7 core layers, among which 6 types of elements, namely buildings, roads, ground parking lots, squares, soft ground and water, do not overlap, do not intersect, and fully cover the entire target area;

[0046] First, create standard CAD layers. Use the AutoCAD "Layer Properties" tool to create layers according to Table 2 or relevant requirements.

[0047] Table 2. List of CAD Layer Names Corresponding to Urban and Rural Material Spatial Element Types

[0048]

[0049] Secondly, the extraction of urban and rural physical spatial elements. Based on the existing topographic survey map and planning design map of the target area in DWG format, the outlines of the features are extracted or drawn using AutoCAD, with each feature's outline being a straight line or an arc.

[0050] Next, feature outline classification. Each feature outline is classified into seven categories according to Table 3: buildings, roads, parking lots, plazas, soft ground, water bodies, and trees. The layer names for each category are set according to Table 1 or relevant requirements. Among these, the six categories of buildings, roads, parking lots, plazas, soft ground, and water bodies must not overlap, intersect, and must fully cover the entire target area; trees are represented by circles, with the center of the circle corresponding to the location of the tree trunk.

[0051] Finally, a standardized DWG file is generated, representing the current status and planned design of the target area. Saved as an "AutoCAD 2010 / LT2010 drawing" file, four files are obtained: a distribution file of current status and planned urban and rural physical spatial elements, and a distribution file of current status and planned trees. The distribution file of current status and planned urban and rural physical spatial elements includes six types of elements: buildings, roads, ground parking lots, squares, soft ground, and water areas. The distribution file of current status and planned trees only includes tree elements.

[0052] Table 3 Classification of Urban and Rural Material Spatial Elements

[0053]

[0054] In this embodiment, the urban and rural physical space renewal of Block X in Beiyang Town, Huangyan District, Zhejiang Province is used as an example for illustration.

[0055] Step S2: Based on the standardized distribution map of urban and rural material spatial elements in the target area, construct GIS geographic information of the current status and planned urban and rural material spatial elements in the target area.

[0056] First, ArcMap's "Add Data" tool was used to import four standardized Dwg files of the target area's existing topographic survey map and planning design map as "Polygon", resulting in four layers.

[0057] Then, use ArcMap's "Export Data" tool to export it as four "shp" files.

[0058] Finally, the ArcMap "Attribute Editor" tool was used to number each element, with element numbering set according to Table 4 or relevant requirements. This resulted in the creation of current status and planning GIS geographic information for the target area based on the classification of urban and rural physical spatial elements.

[0059] Table 4. Numbering Table of Urban and Rural Material Spatial Elements

[0060] Element type Current Status Number Planning Number Buildings A01, A02, ... a01, a02, ... the way B01, B02, ... b01, b02, ... Ground parking lot C01, C02, ... c01, c02, ... square D01, D02, ... d01, d02, ... soft ground E01, E02, ... e01, e02, ... waters F01, F02, ... f01, f02, ... arbor T01, T02, ... t01, t02, ...

[0061] Step S3: Based on the current GIS geographic information of the target area, generate the current urban and rural material spatial element distribution map and corresponding element table of the target area.

[0062] First, generate a map of the current urban and rural physical spatial elements using ArcMap layout view. One step is to display both the current urban and rural physical spatial elements layer 1 and the tree distribution layer 1 together, with the tree distribution layer on top. Second, set the parameters using the "Layer Properties" -> "Symbol System" window. Set "Value Field" to "Layer," "Display" to "Category, Unique Value," and set the fill color for "Symbols" according to Table 5 or relevant requirements. Third, add a legend using the insertion tool. Fourth, export the map of the current urban and rural physical spatial elements using the export tool.

[0063] Then, use ArcMap and Excel to generate a table of current urban and rural material spatial elements. First, export the layer attribute table using ArcMap's export tool. Second, use the attribute table tool in Excel to generate the current urban and rural material spatial element table.

[0064] Table 5. List of Fill Colors for the Distribution Map of Urban and Rural Material Spatial Elements

[0065] Current status Symbol color values ​​(R, G, B) A (36，36，36) B (104，104，104) C (204，204，204) D (235，235，235) E (190，190，190) F (201，201，201) T (122，122，122)

[0066] Figure 2 This is a map showing the current distribution of urban and rural material spatial elements in Block X in this embodiment.

[0067] like Figure 2 As shown, on a planar map represented by a wireframe structure, different colors are used to mark various types of urban and rural material spatial elements. It can be seen intuitively that the above seven types of elements cover the entire urban and rural space from a planar projection perspective.

[0068] Table 6 shows the current urban and rural material spatial elements, listing the corresponding numbers for the above seven types of spatial elements in the target area:

[0069] Table 6. Overview of Current Urban and Rural Physical Spatial Elements in Block X

[0070] elements serial number elements serial number Buildings A01, A02, ... soft ground E01, E02, ... the way B01, B02, ... waters F01, F02, ... Ground parking lot C01, C02, ... arbor T01, T02, ... square D01, D02, ... -- --

[0071] Step S4: Based on the planning GIS geographic information of the target area, generate a distribution map of urban and rural material spatial elements and a corresponding element table for the target area.

[0072] The specific steps are the same as in S3, except that the fill color of the "symbol" is set according to Table 7 or relevant requirements.

[0073] Table 7: A List of Colors for Filling the Distribution Map of Urban and Rural Material Spatial Elements

[0074]

[0075]

[0076] Figure 3 This is a distribution map of the planned urban and rural physical spatial elements of Block X in this embodiment. The table of planned urban and rural physical spatial elements for the target area is shown in Table 8.

[0077] Table 8X: Overview of Urban and Rural Physical Spatial Elements in Block Planning

[0078] elements serial number elements serial number Buildings a01, a02, ... soft ground e01, e02, ... the way b01, b02, ... waters f01, f02, ... Ground parking lot c01, c02, ... arbor t01, t02, ... square d01, d02, ... -- --

[0079] Step S5: Overlay the existing and planned urban and rural material space element type classification GIS geographic information to generate process GIS geographic information of the urban and rural material space element update process in the target area;

[0080] The GIS geographic information of current and planned urban and rural physical spatial elements was analyzed using ArcMap's "Union" tool to obtain a "shp" file document detailing the update process of these elements. The update method attributes for each unit were calculated according to the requirements in Table 8. Table 9 covers six strategies: preservation, internal modification, external modification, repair, reconstruction, and demolition / reconstruction. The characteristics and explanations of each update strategy are shown in Table 10, and the suitable update methods and explanations for each element are shown in Table 11. Details are as follows:

[0081] First, standardize the GIS geographic information of urban and rural physical spatial elements. Load the "shp" file, which represents the update method of urban and rural physical spatial elements, as a layer into ArcGIS. Create three new text fields in the attribute table, named LayerXZ, LayerGH, and LayerGC. Assign the current status layer attribute to the LayerXZ field, the planning layer attribute to the LayerGH field, and record the update method of the elements using the LayerGC field.

[0082] Then, automatically calculate the update methods between different features and mark the update methods of similar features. Using the ArcMap platform, select "VB Script" in the field calculator panel, and enter the following code in the "Pre-logic script code:" box:

[0083] Dim fx

[0084] If [LayerXZ] <> [LayerGH] Then

[0085] fx = [LayerXZ] & "f" & [LayerGH]

[0086] else

[0087] fx = "Manual Judgment"

[0088] end if

[0089] Enter the following code in the "LayerGC=" box:

[0090] fx

[0091] Next, the update method for similar elements is manually determined. Elements with the attribute "manually determined" are determined one by one in conjunction with Tables 10 and 11.

[0092] Finally, create a new text field in the attribute table to record the update method, named "Strategy". Configure it according to the requirements in Table 12, or automatically calculate the feature update strategy. For automatic calculation, select "VB Script" in the field calculator panel, and enter the following code in the "Pre-logic Script Code:" box:

[0093] Dim fx

[0094] If[LayerGC]="AⅠa"OR[LayerGC]="BⅠb"OR[LayerGC]="CⅠc"OR[LayerGC]="DⅠd"OR[LayerGC]="EⅠe"OR[LayerGC]="FⅠf"OR[LayerGC]="TⅠt"Then

[0095] fx = "Ⅰ"

[0096] elseif[LayerGC]="AⅡa"OR[LayerGC]="EⅡe"OR[LayerGC]="FⅡf"Then fx="Ⅱ"

[0097] elseif[LayerGC]="AⅢa"OR[LayerGC]="BⅢb"OR[LayerGC]="CⅢc"OR[LayerGC]="DⅢd"OR[LayerGC]="EⅢe"OR[LayerGC]="TⅢt"Then

[0098] fx = "Ⅲ"

[0099] elseif[LayerGC]="AⅣa"OR[LayerGC]="BⅣb"OR[LayerGC]="CⅣc"OR[LayerGC]="DⅣd"OR[LayerGC]="EⅣe"OR[LayerGC]="FⅣf"OR[LayerGC]="TⅣt"Then

[0100] fx = "Ⅳ"

[0101] elseif[LayerGC]="AⅤa"OR[LayerGC]="BⅤb"OR[LayerGC]="CⅤc"OR[LayerGC]="DⅤd"OR[LayerGC]="EⅤe"OR[LayerGC]="FⅤf"OR[LayerGC]="TⅤt"Then

[0102] fx = "V"

[0103] else

[0104] fx = "VI"

[0105] end if

[0106] Enter the following code in the "Strategy=" box:

[0107] fx

[0110]

[0111] Note: 1) The square brackets “[]” indicate the number.

[0112] 2) The number following the comma is the update method number.

[0113] 3) The diagonal lines represent the update methods for the same type of element.

[0114] Table 10 Overview of Urban and Rural Material Spatial Elements Renewal Strategies and Their Characteristics

[0115]

[0116] Note: 1) The square brackets “[]” indicate the number.

[0117] 2) Preservation refers to maintaining the internal structure and external features unchanged. This includes routine maintenance of all elements. Internal modification refers to altering the internal structure while keeping the external features unchanged. This includes adjusting or improving the building's internal structure and layout. External modification refers to minor changes to the internal structure but alterations to the external features. This includes decorating the building facade and exterior; reducing the number of floors may require necessary changes to the internal structure. Repair refers to maintaining or altering the internal structure and external features to a state of historical value. This includes maintaining and reinforcing a building without changing its external features, or making necessary repairs or key restorations based on historical information. Reconstruction refers to rebuilding on the original site. This includes demolishing buildings and sites of poor quality or those whose appearance clashes significantly with other environmental elements, and rebuilding them in the original location. Demolition and reconstruction refers to transforming one type of physical space element into another, which can be further divided into demolition and new construction. The element before the transformation is called demolition, and the element after the transformation is called new construction.

[0118] 3) Preservation, internal modification, external modification, repair, and reconstruction are renewal strategies for the same type of elements; demolition and new construction are renewal strategies for different elements.

[0119] Table 11 Overview of Urban and Rural Physical Spatial Elements and Commonly Used Renewal Strategies

[0120]

[0121] Note: 1) In the table, “√” indicates the update method of the corresponding column of the spatial element in the row; “--” indicates that the update method of the corresponding column of the spatial element in the row is not defined; “()” indicates auxiliary explanation in parentheses; “[]” indicates number in square brackets.

[0122] 2) Roads, ground parking lots, plazas, and trees do not have internal space, so no internal renovation form is defined; their external renovation mainly refers to surface layer adjustments. Soft land, mostly covered by vegetation, primarily undergoes internal renovation, which mainly refers to soil quality improvement; external renovation is defined as vegetation or surface layer adjustments. Water bodies, due to the close connection between their internal and surface layers, making surface layer adjustments difficult, do not have external renovation defined. Instead, internal renovation is defined as water body management, including interface renewal of other urban and rural material space elements in contact with the water body.

[0124]

[0125] Step S6: Based on the GIS geographic information of the urban and rural material space element update process, generate a map of the urban and rural material space update process and corresponding tables.

[0126] First, generate a map of the urban and rural physical spatial update process using ArcMap layout view. One step is to load the GIS geographic information for the updated urban and rural physical spatial elements. The remaining steps are the same as in S3, except that the "Value Field" is set to "LayerGC".

[0127] Then, use ArcMap and Excel to generate tables of current and planned urban and rural physical spatial elements. The steps are the same as in S3.

[0128] Figure 4 This is a diagram of the urban and rural physical space renewal process in Block X of this embodiment.

[0129] like Figure 4 As shown, based on the current distribution map of urban and rural material spatial elements, each urban and rural material spatial element is marked with a different color to indicate its update strategy.

[0130] The process of urban and rural physical spatial renewal is shown in Table 13 below:

[0131] Table 13X, a table showing the urban and rural physical space renewal process (excerpt).

[0133] Note: Process numbers are automatically generated by ArcMap.

[0134] Step S7: Based on the GIS geographic information of the urban and rural material space element update process, generate a map of the urban and rural material space update process that highlights the current situation and corresponding tables.

[0135] First, use ArcMap layout view to generate a map highlighting the current state of urban and rural physical space update process. This involves: 1) Loading the updated GIS geographic information of urban and rural physical space elements twice. 2) Setting parameters for the lower layer using the "Layer Properties" -> "Symbol System" window: "Value Field" is set to "LayerXZ", "Display" to "Category, Unique Value", and the "Symbol" fill color is set according to Table 4 or relevant requirements. 3) Setting parameters for the upper layer using the "Layer Properties" -> "Symbol System" window: "Value Field" is set to "Strategy", and "Display" to "Category, Unique Value". 4) Setting the update strategy in the "Symbol Selector" according to Table 14. 5) Adding a legend using the insertion tool. 6) Exporting the map highlighting the current state of urban and rural physical space update process.

[0137]

[0138] Then, use ArcMap and Excel to generate tables of current and planned urban and rural physical spatial elements. The steps are the same as in S3, but with an emphasis on the urban and rural physical spatial update process table based on the current situation.

[0139] Figure 5 This is a diagram illustrating the urban-rural material space renewal process based on the prominent existing conditions of Block X in this embodiment.

[0140] like Figure 5 As shown in this embodiment, the current distribution map uses different colors to represent different spatial elements of the current situation. On the basis of the color filling of each plot, diagonal lines, grids and other fillings are superimposed to represent the update strategy of the plot.

[0141] The process of urban and rural physical space renewal based on the current situation is shown in Table 15 below:

[0142] Table 15X: Urban and Rural Physical Space Renewal Process Based on Existing Conditions (Excerpt)

[0144] Step S8: Based on the GIS geographic information of the urban and rural physical space element update process, generate a map of the urban and rural physical space update process that highlights the planning results and corresponding tables.

[0145] First, use ArcMap layout view to generate a map highlighting the urban and rural physical spatial update process of the planning results. The steps are the same as in S7, except that the "Value field" is "LayerGH".

[0146] Then, use ArcMap and Excel to generate a table of urban and rural physical spatial update processes highlighting the planning results. The steps are the same as in S3.

[0147] Figure 6 This is a diagram illustrating the urban-rural physical space renewal process of the outstanding planning results of Block X in this embodiment.

[0148] like Figure 6 As shown in this embodiment, similarly, the planning distribution map uses different colors to represent different spatial elements of the plan, and diagonal lines, grids, etc. are superimposed on the color of each plot to represent the update strategy of that plot.

[0149] The process of urban and rural physical space renewal, highlighting the planning results, is shown in Table 16 below:

[0150] Table 16X shows the urban and rural physical space renewal process highlighting planning results in the X block (excerpt).

[0151] Process Number Planning Number Update strategy 0 a58 External modification [III] 1 a59 External modification [III] 2 e36 Reconstruction [V] 3 e34 Create a new [VI] 4 e35 Create a new [VI] 5 a57 External modification [III] 6 a53 External modification [III] 7 a56 External modification [III] 8 a11 Reconstruction [V] 9 a07 Reconstruction [V] …… …… ……

[0152] Step S9: Based on the current urban and rural material space element distribution map, urban and rural material space renewal process map, planned urban and rural material space element distribution map and corresponding tables, statistical analysis is performed to obtain the street block attribute table. The urban and rural material space renewal process map that highlights the current situation, the urban and rural material space renewal process map that highlights the planning results, and the street block attribute table are combined to form the renewal guideline map for the target area.

[0153] In this embodiment, statistical analysis is performed on each spatial element in the current urban and rural physical space element distribution map to obtain its current area. Similarly, statistical analysis is performed on each spatial element in the planned urban and rural physical space element distribution map to obtain its planned area. Statistical analysis is performed on the urban and rural physical space renewal process map to obtain the retained area, external modification area, reconstruction area, etc. of each spatial element. These data are then summarized into a street block attribute table.

[0154] Figure 7 This is the update guideline diagram for Block X in this embodiment.

[0155] like Figure 7 As shown, the update guideline diagram in this embodiment includes basic information of Block X (block number, location, etc.), a diagram of the urban and rural physical space update process that highlights the current situation, a diagram of the urban and rural physical space update process that highlights the planning results, and the aforementioned block attribute table.

[0156] By following the steps above, we obtain the update guide map for the target region.

[0157] In addition, this embodiment also incorporates the unit price of urban and rural physical space element renewal to form a renewal cost estimation table for Block X, which is beneficial for renewal decision-making.

[0158] The unit price for the renewal of urban and rural physical spaces is shown in Table 17 below:

[0159] Table 17X Block Urban and Rural Physical Space Requirements Updated Unit Price List

[0160]

[0161] Note: 1) In the table, "--" indicates undefined, "Δ" indicates quantity is 0, and "*" indicates price is 0; 2) The data in the table is not used as the basis for actual update calculations.

[0162] Based on the above unit price table, the estimated renovation cost of Block X in this embodiment is shown in Table 18 below:

[0167] Functions and effects of the embodiments

[0168] The method for compiling holographic guidelines for the urban and rural material space renewal process provided in this embodiment has the following outstanding advantages:

[0169] 1) Based on the existing classification of urban and rural material space, from the perspective of direct observation, urban and rural material space elements are divided into 7 categories: buildings, roads, ground parking lots, squares, soft ground, water bodies, and trees, so as to achieve full coverage of ordinary urban and rural material space elements;

[0170] 2) Based on existing renewal methods, a spectrum of renewal methods for urban and rural material space elements is established from two dimensions: the internal and external dimensions of the renewal objects—the constituent elements of urban and rural material space—and the degree of renewal. This spectrum includes seven types: preservation, internal modification, external modification, repair, reconstruction, demolition, and new construction, achieving full coverage of all elements and the entire process of urban and rural material space renewal methods. The spectrum of renewal methods is defined based on the types of urban and rural material space elements before renewal, renewal strategies, and post-renewal types.

[0171] 3) Through the use of linked charts, the state and update process of urban and rural material spatial elements before and after the update are clearly depicted.

[0172] In summary, the method of this invention focuses on the urban and rural material space renewal process by holographically analyzing the distribution and renewal patterns of urban and rural material space constituent elements, thereby enhancing the scientific nature of the core content of the guidelines for urban and rural material space renewal.

[0173] In this embodiment, the method has achieved good results in the conceptual planning application of Block X in Beiyang Town, Huangyan District, Zhejiang Province. The renewal guidelines for Block X compiled by this method integrate urban and rural physical space renewal process charts that highlight the current status and those that highlight the planning results. The block attribute table clearly reflects the status and changes of the physical space elements before and after the renewal of the block. Furthermore, it combines the renewal unit price of urban and rural physical space elements to form a renewal cost estimation table for Block X, providing clear, comprehensive and intuitive information, which is conducive to renewal decision-making and systematically improves the scientific nature of the renewal of Block X.

[0174] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments.
